Seligeria campylopoda is perhaps the most frequently collected species of the genus, and is relatively common along the calcareous parts of the western Cordillera and along the Great Lakes and St. Lawrence Seaway. Otherwise, it has a scattered distribution, known from as far north as Bathurst Inlet and as far south as Colorado and Pennsylvania. It is distinguished in having entire, lanceolate-ligulate leaves with an obtuse tip. The costa is narrow and ends in or just below the apex. The leaf lamina is present in the apex of the leaf. The setae are long and usually curved (most noticeable when moist) in their distal portions. The capsules are longer than broad, being ovate-oblong when dry.
